Lost Creek, United States of AmericaFlight

On July 20, 1983, a Piper PA-31-310 Navajo (registration N234LC) operated by Tenson was involved in an aviation accident near Lost Creek, United States of America in flight. 4 people were killed. Investigators recorded the probable cause as: Occurrence #1: loss of engine power (reason undetermined); Occurrence #2: forced landing (aircraft weight and balance exceeded by pilot in command); Occurrence #3: in-flight collision with object (weather conditions: low ceiling and fog; objects: wire… This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

A single-engine aircraft with 4 occupants and cargo crashed after reporting a left engine problem. The aircraft struck a power line and trees, then burned. Investigation found weight exceedance and weather factors.

Accident Summary

The aircraft departed with 4 occupants and an estimated 596 lbs of cargo. After takeoff, air traffic control noted a slower-than-expected climb. At approximately 4,200 feet MSL, the crew reported a left engine problem and indicated they could not return to the departure airport, expressing a desire to continue southwest. ATC vectored the aircraft toward Weston Airport, which had no instrument approach. Following the reported engine malfunction, the aircraft entered a gradual left turn. Radio contact was lost about 8 minutes after takeoff.

Witness Account

A ground witness observed the aircraft come over a hill with the sound of an engine at high power. Shortly thereafter, the aircraft collided with a power line cable, then crashed into two trees, impacted the ground, and burned. All four occupants were killed.

Investigation Findings

Examination of the wreckage revealed no significant preimpact failures. The aircraft was estimated to be approximately 400 lbs over its maximum certificated gross weight. Official findings listed multiple occurrences:

  • Loss of engine power during climb to cruise (reason undetermined)
  • Forced landing during approach (aircraft weight and balance exceeded by pilot in command)
  • In-flight collision with objects during approach (low ceiling, fog, wire/transmission line, trees)
  • In-flight collision with terrain during uncontrolled descent

Probable Cause

Occurrence #1: loss of engine power (reason undetermined); Occurrence #2: forced landing (aircraft weight and balance exceeded by pilot in command); Occurrence #3: in-flight collision with object (weather conditions: low ceiling and fog; objects: wire transmission and trees); Occurrence #4: in-flight collision with terrain/water (descent uncontrolled).
